About the '=' Padding

Base64 encoding requires the input length (in bytes) to be divisible by 3. If it's not, padding is added: One '=' character is added when the input length modulo 3 equals 2. This ensures the encoded output is properly aligned.

Step 1: Map ASCII Characters to Binary

ASCII Character	Binary Value
m	01101101
e	01100101
t	01110100
e	01100101
o	01101111
r	01110010
o	01101111
l	01101100
o	01101111
g	01100111
i	01101001
c	01100011
a	01100001
l	01101100

Step 2: Group Bits into 6-bit Chunks

The binary string is grouped into 6-bit chunks for Base64 encoding:

011011 010110 010101 110100 011001 010110 111101 110010 011011 110110 110001 101111 011001 110110 100101 100011 011000 010110 1100

Step 3: Convert Binary to Base64

Binary Value	Base64 Character
011011	b
010110	W
010101	V
110100	0
011001	Z
010110	W
111101	9
110010	y
011011	b
110110	2
110001	x
101111	v
011001	Z
110110	2
100101	l
100011	j
011000	Y
010110	W
1100	w

When combined, these characters form the encoded string: "bWV0ZW9yb2xvZ2ljYWw="
